The amplification that Fig. 5 shows by the zone of a kind of embodiment of device 2 of the present invention illustrates in detail, and described device has the laser-projector 4 that is fixed on the support 6 and is placed in laser radiation mechanism 8 on the side that deviates from laser-projector 4 of support 6.Laser-projector 4 has laser diode 41, and this laser diode is in operation and controls by the unshowned electronic installation in Fig. 5 that is fit to, for generation of laser beam 5.
Described laser beam 5 is arranged in lens combination 42 in the laser-projector 4 through at least one, and this lens combination makes the laser beam 5 in other words focusing that suitably is shaped.Turn in other words prism 44 by the deviation mirror that is fit to, laser beam 5 is redirect on the grating 43 of optics, this grating produces the laser beam pattern 12 that is suitable for optical measurement by the light refraction of laser beam 5.
Arranged in a side that deviates from laser-projector 4 of support 6 and basically to be configured to the in other words laser radiation mechanism 8 of frustum-like shape or prism-frustum-shaped of funnel-form; this laser radiation mechanism has opening at it equally on a side of support 6; this opening is so directed, so that the laser beam pattern 12 that penetrates via the opening 6a in the support 6 can enter into laser radiation mechanism 8.Laser radiation mechanism 8 its dorsad the outgoing side 13 of support 6 and laser-projector 4 be open wide be provided with in other words the protective disc that for laser emission, can penetrate; thereby laser beam pattern 12 can penetrate from laser radiation mechanism 8, then is mapped in Fig. 5 on the unshowned object to be measured 14.
The center main beam 12a(0 order diffraction beam of laser beam pattern 12) opening that is mapped to laser radiation mechanism 8 is in other words in the zone of protective disc; in this zone, arranged catoptron 22, this mirror reflects center main beam 12a and so prevented that the radiation of laser beam pattern 12 from strengthening and therefore proemial main beam 12a from laser radiation mechanism 8, penetrate.Main beam 12a returns towards the direction of support 6 and laser-projector 4 by catoptron 22 and reflects.
The reflection main beam 12b be mapped in following position laser radiation mechanism 8 on the end of support 6; on the described position in laser radiation mechanism 8 and be arranged in thereafter the support 6 and constructed the second opening 6b, 8b; the main beam 12b of reflection penetrates from laser radiation mechanism 8 by described the second opening, and via support 6 be mapped to 6 that arrange later at support, for example be configured on the lens 20 of Fresnel Lenses.Described lens 20 focus on the main beam 12b that reflects on the monitor diode 18 that is arranged in lens 20 back.
In embodiment illustrated in fig. 5, lens 20 and monitor diode 18 are integrated in the described laser-projector 4.Monitor diode 18 and lens 20 also can be configured to the independent device that is independent of laser-projector 4 and be fixed on the support 6.
By assessment by the signal that sends on the monitor diode 18, can monitoring laser protection mechanism 8 have situation and a correct orientation.
Be in operation, laser-projector 4 is preferred at first to be moved with the not dangerous power that has reduced.If the main beam 12a with laser emission 12 so reflexes on lens 20 and the monitor diode 18 by catoptron 22; so that monitor diode 18 is sent the signal with intensity given in advance; that has just been guaranteed; laser radiation mechanism 8 is correctly directed with catoptron 22, and the power of laser-projector 4 can be brought up to as implementing to measure necessary power.
Can cut off in the following cases on the other hand laser-projector 4 and send alerting signal: be inconsistent in other words to deviate from described predetermined value greater than tolerance given in advance by laser emission and predetermined value that monitor diode 18 detects; because laser radiation mechanism 8 is correctly not directed, thereby the main beam 12a of laser emission 12 is not projected to as defined on the monitor diode 18.
Security of going back the described device 2 of further raising like this is because prevented when correctly installation is with orientation that in laser radiation mechanism 8 danger of laser-projector 4 from moving.
In laser radiation mechanism 8, constructed extraly beam trap 24; this beam trap absorbs the laser beam 12c by lens 20 and/or monitor diode 18 reflections; penetrate from laser radiation mechanism 8 uncontrollably in order to prevent the beam 12c that reflects, it may be distorted measurement result and/or may be dangerous concerning the operator.
Fig. 6 shows a chart, in this chart with respect to time t(x axle) drawn the luminous power P(y axle that is sent by laser-projector 4).
Laser-projector 4 is controlled with prepulsing (Vorpuls) VP with t1 turn-on time, thus its generation have power P 1 and turn-on time t1 laser pattern 12.Subregion, preferred main beam 12a such as the front of the laser pattern 12 that produces by prepulsing VP are detected by catoptron 22 reflections and by monitor diode 18 as described in Fig. 5.
If when the signal of monitor diode 18 is assessed, there is not the discovery feature fault, that is to say if being within the scope given in advance with ratings given in advance by the measured intensity of this monitor diode of the laser 12b that is detected by monitor diode 18, then so control laser-projector 4 with the main pulse HP with larger turn-on time of t2 so that its generation have higher power P 2 and larger turn-on time t2 laser pattern 12.In other words projection of real measurement uses the laser pattern 12 that produces by main pulse HP to implement.
On the contrary, be in during the prepulsing VP outside (tolerance) scope given in advance if reflex to intensity laser 12b on the monitor diode 18, that detected by this monitor diode, then determining functional fault and stoped the main pulse HP for generation of the laser pattern 12 of the intensity P2 with raising to send.In other words, send in other words fault-signal of alerting signal, in order to point out functional fault to the operator.
Since real have larger power P 2 and long turn-on time t2 main pulse HP before at first output have the power P 1 that reduces with respect to main pulse HP and shorter turn-on time t1 prepulsing VP and stoped reliably and sent main pulse HP; if so when surveying and assess the laser pattern 12 that produces by prepulsing VP, determined functional fault; then when laser-projector 4 operation, further improve security, because identified reliably the functional fault of laser radiation mechanism 8 particularly and stoped the harm operator's of laser-projector 4 operation.
Fig. 7 shows the skeleton view of the first embodiment of catoptron 22, and this catoptron is positioned on the side of dorsad support 6 of laser radiation mechanism 8, so that the main beam 12a of reflection diffraction Figure 12.
Scheme as an alternative, described catoptron can be configured to the disc 24 that is made of lighttight unreflecting material, in central area 26, reflecting material being installed on the lighttight unreflecting material on the one side at least, so that the laser emission 12 of reflection diffraction figure and particularly main beam 12a.
Fig. 8 shows the second embodiment of catoptron 22.Catoptron 22 consists of by a ring 30 of being made by lighttight unreflecting material in this embodiment, and catoptrical material 32 is inserted in the described ring 30 in the center, thereby catoptron 22 at least one end face in its end face has foveal reflex zone 32.
When design reflectivity mirror 22 and particularly reflecting material and absorbing material, should note; in other words lighttight material 26 residual, that pass reflection, 28,30,32 radiation beam transmissive are all the time less than the maximal value of stipulating for laser radiation, in order to avoid reliably the laser emission of dangerous intensity to penetrate from laser radiation mechanism 8.
Those skilled in the art understand, catoptron 22 be not enforceable for described function round-shaped shown in Fig. 7 and 8.Or rather, catoptron 22 can have every kind of arbitrarily shape, if foveal reflex zone 26,32 by unreflecting edge 28,30 surround.
